Engineering Note on Biogas & Landfill Gas Tolerance

Unlike pipeline natural gas, renewable gases can fluctuate in composition and may contain corrosive contaminants. Gas generator configurations for biogas and landfill gas should therefore be selected according to the actual fuel composition and the applicable engine specifications.

CH₄ (Methane Content)

Selected engine configurations can support methane concentrations down to CH₄ ≥ 40%, with dynamic air-fuel ratio control.

H₂S Resistance

Selected engine configurations can tolerate H₂S levels up to 200 ppm. Higher concentrations may require upstream gas treatment.

Siloxanes & Moisture Control

Multi-stage condensate traps and optional activated carbon scrubbers can help control moisture and siloxane-related deposits within the engine system.

Fuel Gas Types and Operational Considerations

Natural Gas Generators

Pipeline natural gas typically provides high methane content and a relatively stable supply, making it an ideal choice for continuous industrial operation, peak shaving, and commercial standby power.

Key Focus:
• Gas Train Safety: Equipped with reliable safety shut-off valves and comprehensive gas train protection.
• Inlet Pressure Control: Regulated gas inlet pressure, typically 10–300 kPa depending on the engine model.
• Engine Control: Advanced anti-knock control parameters precisely matched to the selected engine.

Typical Applications: Manufacturing plants, data center backup, municipal utilities, and urban distributed power generation.

Biogas and Renewable Gas Generators

Biogas produced from anaerobic digestion, agricultural livestock waste, or municipal wastewater treatment contains varying levels of methane, carbon dioxide, moisture, and corrosive trace elements.

Key Focus:
• H₂S Corrosion Control: Specialized measures to mitigate internal corrosion caused by hydrogen sulfide.
• Moisture Management: Strict control of moisture condensation within the fuel system manifold.
• Air-Fuel Ratio Adjustment: Dynamic adjustment capabilities to accommodate seasonal or biological shifts in methane concentration.

Upstream Gas Treatment Guidance: Where contaminant levels exceed strict manufacturer thresholds, our engineering team integrates upstream gas treatment solutions:
• Moisture separators and gas chillers
• Activated carbon and iron sponge H₂S scrubbers

Gas Train & Fuel Safety Systems

Gas Filtration

Removes particulates and suspended contaminants before gas enters the pressure regulation system.

Pressure Regulation

Maintains gas pressure within the engine's specified operating range.

Safety Shut-Off Valves

Isolate the gas supply during emergency stops or detected system faults.

Leak Detection

Monitors gas leakage and supports automatic safety shutdown where required.

Moisture & Condensate Control

Helps prevent liquid accumulation in the gas manifold and fuel system.

Control, Monitoring, and Engine Protection

Engine Monitoring

Real-time monitoring of oil pressure, coolant temperature, exhaust temperature, boost pressure and other key parameters.

Fuel Safety Interlocks

Gas supply can be shut off in response to abnormal gas pressure, flame-out or detected gas leakage.

Step-by-Step Gas Generator Selection Guide

Calculate Electrical Load and Profile: Assess continuous operating loads, starting currents for large electric motors, and potential future load expansion.

Analyze Fuel Composition and Quality: Verify methane concentration, heating value, and potential corrosive contaminants (submitting a gas chromatography report is strongly recommended).

Verify Gas Supply Pressure and Flow: Confirm that the gas delivery pressure at the generator skids meets the minimum requirements of the pressure-regulating train.

Define Operating Duty: Specify whether the unit operates as prime power (continuous baseload) or standby backup.

Evaluate Environmental and Acoustic Constraints: Determine if the unit will be installed indoors, within a sound-attenuated enclosure, or inside an outdoor ISO container.

FAQ

Q: What fuel gases can these generators operate on?

A: Our systems are engineered for natural gas, biogas, landfill gas, sewage gas, and select industrial off-gases. Suitability depends on meeting specific methane number, heating value, and cleanliness thresholds defined during the engineering review stage.

Q: How does gas pressure affect generator performance?

A: Gas pressure must remain within the specified operational window of the engine's fuel management system. Inconsistent pressure or pressure outside the acceptable range can cause unstable combustion, power derating, or automatic safety shutdowns. Additional pressure-reducing or booster equipment may be integrated if site conditions require it.

Q: Can gas generators be synchronized for parallel operation?

A: Yes. With appropriate digital controllers and motorized switchgear, multiple gas generator sets can operate in parallel to handle larger electrical loads, provide redundant backup, or manage automated load-sharing configurations.

Q: What information is required to receive an accurate quotation?

A: To prepare a precise proposal, please provide the required electrical power output (kW), voltage, frequency, operating mode (prime or standby), fuel gas type, methane content, available gas pressure, and installation site location. Submitting a fuel gas analysis report is strongly recommended for biogas or non-pipeline gas projects.

Q: What is the typical delivery lead time?

A: Standard open or silent gas generators take 30 to 45 days. Customized containerized units or specialized biogas projects typically require 60 to 90 days depending on engineering complexity.

Q: Do these generators meet international emission standards?

A: Emission configurations can be selected according to the engine specification, fuel type and local regulatory requirements. AFR control and optional catalytic after-treatment systems can be provided for projects with specific NOx and CO emission limits.

Q: What after-sales support and spare parts do you provide?

A: We offer global remote technical support, installation guidance, and fast-shipping replacement parts—including spark plugs, ignition coils, filters, and gas train components—to ensure minimal downtime.
